Abstract Background Breast cancer patients with early-stage disease are increasingly administered neoadjuvant chemotherapy (NAC) to downstage their tumors prior to surgery. In this setting, approximately 31% of patients fail to respond to therapy. Th

Significance: Diffuse optical imaging (DOI) provides in vivo quantification of tissue chromophores such as oxy- and deoxyhemoglobin (HbO2 and HHb, respectively). These parameters have been shown to be useful for predicting neoadjuvant treatment respo

We present a high-optode density continuous-wave (CW) wearable diffuse optical device for the investigation of hemodynamic responses of locally advanced breast tumors. Initial results from tissue-simulating phantoms and a normal volunteer study are d

Diffuse optical imaging (DOI) techniques provide a wide-field or macro assessment of the functional tumor state and have shown substantial promise for monitoring treatment efficacy in cancer. Conversely, intravital microscopy provides a high-resoluti

Spatial frequency domain imaging (SFDI) is a widefield, noncontact, and label-free imaging modality that is currently being explored as a new tool for longitudinal tracking of cancer therapies in the preclinical setting. We describe a two-layer look-

Spatial Frequency Domain Imaging (SFDI) is a Diffuse Optical Imaging (DOI) technique that is well suited for preclinical functional imaging. Recently, we have shown that SFDI can successfully be used for longitudinal monitoring of a prostate subcutan

We present a Monte Carlo (MC) method to determine depth-dependent probability distributions of photon visitation and detection for optical reflectance measurements performed in the spatial frequency domain (SFD). These distributions are formed using

Frequency Selection with Optical Property Uncertainty Estimates for Spatial Frequency Domain Imaging
Publikováno v:
Biophotonics Congress: Biomedical Optics Congress 2018 (Microscopy/Translational/Brain/OTS).
We present a method to generate optical property uncertainty estimates from knowledge of diffuse reflectance measurement errors for spatial frequency domain imaging. Our method can help optimize spatial frequency selection for a given application.

Bone blood perfusion has an essential role in maintaining a healthy bone. However, current methods for measuring bone blood perfusion are expensive and highly invasive. This study presents a custom built near-infrared spectroscopy (NIRS) instrument t
